When is a good time to plant hydrangeas in South Florida and is there a specific bloom that is hardier in this region?

BloomStruck Hydrangea has above average heat tolerance for bigleaf hydrangeas. In your area, I would plant it in a place where it gets afternoon shade. Even consider planting a hydrangea in a container so you can easily move it around the garden if one spot doesn’t work out. And, take a look at our container gardening guide for information on selecting potting mix, fertilizing, watering, and more.
